Hi all, A quick question here. AMS' VCF has two lowpass filter types - one with and one without resonance. But when I use the resonance parameters, they seem to affect only if I select the non-resonant lowpass. Is it a bug or do I badly misunderstand something? I have been looking for AMS' documentation on that VCF but no luck... Thanks in advance for any info! Aurélien

Building Ardour 4 - Gnu/Debian Wheezy.

by OvO OvO

Hello. Ardour 4 is out, as you surely know. As usual since 6 or 7 years, still no possibilities to make a payment without paypal.Some of us don't want to use paypal.So you can't have a «ready to run» binary if you don't pay (fair, it's free as free speech, not free beer) but you can't pay.And now a new feature for the «you don't pay» users, a demo version that turns silent after 10 minutes (nice feature, really ! Amazing ! so clever to spend time on that, than to add a payment system) So here is how i build from source on a Gnu/Debian Wheezy. Open the tar file. ./waf configure --with-backend=alsa,jack --no-jack-metadata --prefix=/6_years/people/asking/paypal/alternative/so_hard_to_do Adapt the options for you needs.You can see the options with : /waf configure --help |less Check the errors when you configure, and install the missing packages.Use your package manager accordingly to your Gnu/Linux distro.On Gnu/Debian, apt or aptitude.Add or remove packages if you already have them or not.The configure should tell you what you need/miss aptitude -R install libraptor2-dev libsndfile1-dev libgnomecanvas2-dev libsigc++-2.0-dev libcairo2-dev liblrdf0-dev libfreetype6-dev libfftw3-dev libglibmm-2.4-dev libcairomm-1.0-dev libpangomm-1.4-dev libatkmm-1.6-dev libart2.0-cil-dev libgnomecanvasmm-2.6-dev liblo-dev librasqal3-dev libogg-dev libflac-dev libvorbis-dev libsamplerate0-dev libaudio-dev liblv2dynparam1-dev libserd-dev libsord-dev libsratom-dev liblilv-dev libsuil-dev librubberband-dev vamp-plugin-sdk libaubio-dev libjack-dev liblilv-dev Once the configuration is done without errors : ./waf build -jX X=thread your cpu can handle. example : ./waf build -j8Wait a little, it's fast on recent CPU with cores. Then go to the directory you've declared in the configure --prefix= For example : cd 6_years/people/asking/paypal/alternative/so_hard_to_doYou'll find directories : bin etc lib share cd bin ./ardour4 Work perfectly on a Gnu/Debian Wheezy. Best.

Calf Envelope Filter = Ardour crash

by jonetsu＠teksavvy.com

Hello, I have compiled the Calf plugins from git, minutes ago. I use the 5-band equalizer and reverb w/o problems, using Ardour 3.5.403. I add the envelope filter to a track and immediately press play. Ardour vanishes instantly from the screen. Is this still a fftw bug ? Cheers.

Create A Negative of the sound

by Set Hallstrom

Hi, Is there any software that can create a negative of the sound? I'm thinking of taking an arbitrary frequency bandwith, pick a center and invert it, so that bass becomes high, and high becomes bass? I have the feeling this is an impossible task due to the nature of sound. But i dreamed it up last night, so it HAS to be possible somehow, if i can trust the comic books of the fifties containing TabletPC, space-rockets and wireless phones. :D In the dream, they would use some software similar to the ones used to remove noise from audio, where you see an abstract colour representation of the sound, and you can kindof "paint" out the undesired noise. Then they would just, flip the coulours arround. We first listened to a drum track (in the dream, yeah?), and the highhats would sound like kickdrum and the kickdrum soundet a bit like highhats. Then they applied it on the entire song track (still in a dream ok) and it sounded so good that my enthusiasm woke me up... Thankfull for any explanations and ideas, Yours dreamfully, -- Set Hallstrom AKA Sakrecoer http://sakrecoer.com

Recording a video with High quality audio

by Ivan K

I would like to make a video of a performance of acoustic music. I have a webcam on my computer, but rather than use the microphone that is on the webcam, I would prefer to use my ART USB Dual TubePre microphone preamp plugged into the S/PDIF of my M-Audio 2496. Is there any application that can record video from a webcam but use an audio input other than the built-in mic on the cam? Thanks;

LAC2015 Aftermath: The LAC2014 Percussion Combo Kit now available

by Frank Neumann

[The posting to LAA is awaiting moderator approval for 2 days, so I take the liberty of cross-posting] Hi, during LAC2015 in Mainz last week, I gave a lightning talk on what I called "The LAC2014 Percussion Combo". It was a presentation about a little field recording session conducted one year earlier, during LAC2014 in Karlsruhe, and what I made out of it. The data is now finally online, including the actual sample library kit (individual wav files) with a mapping file for Hydrogen, a tiny demo pattern, and a demo song called "That's LAC" that came to life "out of nowhere" - well, I guess I'll simply call it my first Linux Audio "release" ever :-). Read all about it here: http://linuxaudio.de/wp/?p=158 Thanks go out to the individual artists whose performance I had the honour to record: Marc Groenewegen, Pjotr Lasschuit, Nils Gey, Bernard Tressol, Michael Seeber, Stefano Pedrinazzi, Marie-Kristin Meier, and Fernando Lopez-Lezcano. Enjoy, Frank
